SQLite migration causes NoMethodError: undefined method `to_sym' for nil:NilClass

Issues

Hello guys! Here is my relation class code:

class Code < ROM::Relation[:sql]
  schema do
    attribute :id, Types::Int
    attribute :code, Types::String
    attribute :used, Types::Bool

    primary_key :id
  end
end

All the other things are by default configured for ROM-Rails. Nothing changed except adding relation into new Rails project with integrated ROM-RAILS with ROM-SQL

What can be the problem here?
